CAR VENTILATOR.

Application led March 31, 1924.

l 1o al! whom it' may concern.'

Be it-lrnowr. that I, TWILLIAM E. `W1NE, a citizen of the 'United Statesof America, residing at Toledo, in the county of Lucas and State ofOhio, have invented certainv new and useful Improvements in CarVentilators, of which the following is a specilication.

My invention relates to new and useful improvements in ventilators, andespecially to ventilators that are adapted for use on freight cars.

One of the objects of the present invention is to construct a ventilatormade up of essentially two side pieces, in which are mounted cross barsin the form of angles, between which are loe-ated shutters, also `formedof angles, the latter being movable so to open and close the ventsbetween 29 the cross bars..

Still another object of the invention is to provide a ventilator-wherein certain lugs hold the cross bars in position while further lugsin the form of tracks guide the movable shutters when operated.

lhen the term angle is used, it refers generally to metal plates thatare 1n the 'form of angles, these being readily purchased in the openmarket, and when arse ranged for use in the ventilators, simply have tobe out to length, and in one form out at their both vends to formsupporting` projections, as we ventilator.

Still another object of the invention is to provide a ventilator whereinthe same may be formed of crossbars and shutters consisting of angularplates, the former iff-'l supported and the latter supported and guidedin the two side pieces, in which in turn are cast projections andtracks, so that the ventilator as a whole will be veryk Serial No.703,170.

economical to make and also cheap to repair, when necessary.

Still another object of the invention is to form a ventilator withshutters and cross bars wherein the shutters may be quickly and easilyoperated to an open and closed position.

With these and other objects in View, the invention consists in certainnew and novel constructions and combination of parts as will behereinafter more fully described and pointed out in the claims.

Referring now to the drawings showing a preferred embodiment of myinvention,

F ig. l is a front view of my improved ventilator as applied to the endof a freight car;

liig. 2 is a vertical sectional view showing the shutters in theirclosed position;

`Fig. 3 is a similar View showing the shutters in the open position;

F ig. l is a detail fragmentary View of the locking dog;

Fig. 4a is a further fragmentary view of the locking means showing thedog in its other extreme position;

Fig. 5 is a detail fragmentary View of one of the side pieces, as shownin Figs. 2- and 3, the shutters being removed for the sake of clearness;

Fig. 6 is a vertical sectional View of the ventilator showing a slightlymodified form, the shutters being in their closed position;

lig. 7 is a view similar to Fig. 6, with the shutters moved to theiropen position;

F ig. 8 is a fragmentary perspective of one end of the movable shuttersto show how they are supported;

Fig. 9 is a fragmentary sectional detail.

view taken on line 9-9 of Fig. G; and

Fig. 10 is a View similar to Fig. 5, but showing the modified sidepieces as used in the modified forms shown in Figs. 6 and 7. Referringnow more in detail to the drawings, Figs. 1 to. 5 inclusive, there isshown the sheathing l of a freight car in which is assembled theventilator 2 comprising the side pieces 3 and 4, the fixed cross bars 5,the movable shutters 6, the tie bars 7, the operating bar 8, the handle9 and the dogs l0 pivotally mounted on the bar E).

Riveted to the tie bars a are the metal straps 11 which in turn aresecured by rivets 12 to the plurality of movable shutters 6, as may beclearly seen in Fig. 2.

Referring now more specifically to the cross bars 5 and the shutters 6(and first to the cross bars 5), it will be seen that they each consistof a plate having the legs 13 and 1e, the angle between the legs beingninety degrees, and the depth of each leg being such that it extendsnearly across the side pieces 3 and 4, when placed with the apex in thevertical position as shown in Figs. 2 and 3. These plates are readilypurchasable in the open market, and of course, may be readily cut to thedesired length. They are supported at their opposite ends by the twoside pieces 3 and e, as will be referred to shortly. r1`he movableshutters 6 are formed of similar angles, as heretofore mentioned, andriveted thereto are the straps 11, the shutters being arranged so thattheir one leg will slide along the one leg` of the cross bar whenoperated, as shown in Figs. 2 and 3.

rlhe arrangement of the tracks and lugs is such that when the shuttersare pulled downwardly to a closed position, they will tend to slightlywedge against the adjacent legs of the cross bars as may be seen bycomparing Figs. 2 and 3.

Referring now specifically to Fig. 5, there is shown the small t-shapedlug or projection 15 and the lug 16, spaced from the lower leg of theprojection 15, the spacing being such that it will receive the leg 13 ofthe cross bar 5. A further guide or track 17 is shown which issubstantially rectangular, with the exception that the fourth side isomitted, and it is to be noted that the lower leg 18 of this track 17 issubstantially at an angle of 45 degrees to the edge of the side piece,but the upper leg of the V-shaped lug 15 does not parallel the leg 18,it being in a slight angular relation therewith. rlllie object of havingthis slight angular relationship is that, when the movable shutters Gare moved from their open position, as shown in Fig. 3, to the positionas shown in Fig. 2, the one leg of each shutter riding along the upperleg of the il-shape projection 15 will cause the opposite leg of eachmovable shutter to approach the adjacent leg of each cross bar, andfinally contact therewith, to thus slightly wedge the shutters in theirclosed position and prevent any lateral or loose movement.

As far as the specification has proceeded, it will be understood thatthe if-shaped projection 15, the lug 16 and the lower leg 18 of thetrack 17, form a holding means for the one end of the cross bar, while asimilar arrangement is provided on the opposite side piece so that thecross bars may be readily assembled and held in the frame. Furthermore,the upper leg of each of the V-shaped projections 15 form a track andsupport for the shutters as will be readily understood. Any number ofcross bars and shutters may be provided for, depending on the height ofthe side pieces.

For simultaneously moving the shutters, the tie bars 7 are provided, asheretofore referred to; they having a bearing 19 formed in their lowerends through which passes the rod 8.

Referring for a moment to Fig. 2, it will be seen that the rectangulartrack 17 at the bottom of each side piece, has the base piece 9.0 formedintegrally with the lower leg 18 and slightly curved, as at 21 for thereception of the pivotal dog 10. The handle 9 is provided at its one endwith the slot 22 and the projecting pins 23 and Q11, while the bar S isprovided with the notch 25 as may be seen in Figs. 2, 3 and 1i, so thatthe handle 9 may be operated either from a downwardly hanging positionas shown in Fig. 4, or from an upright position, as shown in Fig. 3, itbeing simply necessary to engage either the pin 28 or 24C with the notch25 to rotate the shaft 8 and force it upwardly and inwardly atapproximately an angle of forty-tive degrees to open the vents. In otherwords, move the shutters upwardly and inwardly to open the vents, orclose the vents by moving the shutters downwardly and outwardly, in bothinstances, the dogs 10 travelling along the bases 20, as may beseen inFigs. 2 and B.

The curvature of the bases as at 21, retains the dogs from escaping fromthe bases, which arrangement of the dogs also provides a locking meansfor the shutters in their open or close-d positions. V'Vith theventilator formed in this manner, the shutters and cross bars may bequickly and easily assembled; the shutters may be easily and readilyoperated to open and close the vents formed by the cross bars, and theshutters may be easily locked in either position. Furthermore, thecooperating tracks, lugs and guides, support the cross bars and shuttersand also provide guideways for the movable shutters, and by making oneof the lugs at an angle to the other, as above referred to, the shutterswhen drawn to a closed position, have a slight wedging action, thusassisting in locking the shutters and providing against loose movementor rattle.

A slightly different arrangement of the shutters is shown in Figs. 6 to10, the principle being the same, but the path of movement of theshutters being a horizontal one rather than a combined upward and inwardmovement. This is made possible by a slightly diilerent arrangement oftracks 2G which may be understood by referring to Fig. 1()` for the sakeof clearness. Each track comprises the angular way 27, the base 28,in

which is provided the depressions 29, and the slightly inclined end 80.A lug 31 is shown parallel to the portion of the track 2T so that aspace is provided to receive one end ot' one of the legs of the crossbar 32, this cross bar 32 being similar to the cross bar 13 in the otherform.

Projecting downwardly from the center of the portion 28 of the track 26is a further guide 33 with a leg 34 at right angles thereto, to tightlyhold the cross bar 32 in position, the portion also forming a supportfor one leg of the movable shutter $35. rlhis shutter 35 is similar tothe shutter G with the exception that its ends are cut as shown in Fig.S, the portions as at 39 and i0 being cuit away, in each leg of theangle to leave the projections i-l, which projections ride along thebases ot the tracks Z8 and rest in the depressions 29, that is, thecenter one and the one at the right hand side, or the center one and theone on the left hand side, depending upon whether the shutter is in itsopen or closed position. In a like manner, these shutters 35 are movedby tie bars 12, and riveted near their ends ai'e the straps 43, which inturn are riveted as at de to the shutter.

This form of ventilator is also quickly and easily assembled. Inoperation, an inward movement of the bars i2 will cause the shutters toride along the tracls from the position shown in Fig. 6 to the positionshown in Fig. 7, to thereby open the vents, while an outward pull of thebars will cause the movable shutters to travel outwardly and contactalong their upper edge with one leg of the cross bars to thereby closethe ventilator. l Y

From the foregoing, it will be seen-that the ventilator, whetherconstructed as shown in the one form or the other, comprises cross barsformed o angle iron and shutters formed of angle iron, which may beeasily purchased in the open market. Furthermore, the lug or guides, andprojections may be so arranged that the shutters move away and towardsthe cross bars either in an inclined movement or in a straight inwardand outward movement to thereby open and close the vents as the occasionmay require. f

Furthermore, an arrangement is shown for easily operating the shuttersand for* locking them in either of their two positions. In the severalviews, I have shown the ventilator as installed in a freight car withoutany special metal upper and lower rail, but it will be understood thatthese portions might be used if it is ever desired.

The parts are relatively light in weight, relatively cheap to purchase,and may be readily assembled. At the same time, I have provided aventilator which will withstand the hard usage incident to railroadinstallations, and prove highly effective in service.

Many slight changes might be made without in any way departing ironi thespirit and scope of the invention.
